Scott Stoops of FlyRC Magazine says:

I hesitate to describe any RC product using the term "revolutionary", but in the case of the new Spektrum DX7, it is the perfect word to describe a product that has the potential to fundamentally change the world of RC. Some may think I am being overly dramatic, but I suspect that after reading this article, you just might agree with my take on the Spektrum DX7...

Conclusion:

In my 23 years of RC modeling, I’ve seen technology that claimed to be the next great thing come and go many times over. Some products, however, make their mark in such a way that they completely redefine the market. I would offer that the Spektrum DX7, with its 2.4GHz full-range DSM2 technology, is such a product. After operating the DX7 for the last few months, I’m completely sold on the DX7—not one single glitch in well over 150 flights.... the DX7 is an absolute steal..... Extract from a review by Scott Stoops of FlyRC Magazine

  • Airplane and Heli software

Spektrum DX7 Overview

With the DX7 you’ll be able to fly anything from micro electric helis, to big gas-powered IMAC planes without regard to frequencies and free from fear of interference. Calling this kind of thing “revolutionary” just doesn’t cut it. It is nothing less than a quantum leap in RC technology that will change how you fly forever. Never again will the availability of a frequency pin dictate when you can take off. Never again will you have to ask, “What channel are you on?” Never again will your flying experience be interrupted by model-generated RF noise, interference from commercial broadcast towers, or anyone on another RC system.

****Warning for DX7 users****

DX7 users that mount a transmitter stand to the unit must ensure that the stand does not touch the Bind/Range check button when collapsed.

Pressure on this Bind/Range Check button from the transmitter stand will cause a reduced range signal which could cause the Plane/Heli to go into failsafe and possibly crash.

Mode 1 vs Mode 2 Transmitters

 
Transmitter Stick Configurations:

Mode 1 - Throttle and Aileron Control on the Right Stick, Elevator and Rudder on the Left Stick. This is predominantly used in Australia and Europe.

Mode 2 - Elevator and Aileron on the Right Stick, Throttle and Rudder on the Left Stick. This is predominantly used in the United States.

There is no clear benefit to each configuration as everyone’s use and preference is different. Mostly it comes down to your friends and what they are already using so they can help you if required. A Mode 2 user cannot easily teach a Mode 1 flyer.
